This volume is part of a set intended to document the data collection of the 1990-91 Schools and Staffing Survey (SASS). Volume 1 provides the essential background information for the survey, and Volume 4 is the restricted use codebook for the SASS Bureau of Indian Affairs data. Volume 2 is the restricted-use codebook for the survey, and this volume contains the public-use codebook. It contains the variable names and position numbers for all survey and sampling variables. All data variables have been imputed to compensate for item nonresponse. Imputation flags are given at the end of each SASS component's codebook. In the public-use codebook, individually identifying data have been recorded or altered to prevent identification. The volume discusses created variables and contains user notes for the files. Three appendixes contain the Teacher Demand and Shortage Public and Private School Codebook. the Public and Private School Administrator Codebook, and the Public and Private School Teacher Codebook.
